Gareth noted that we located the problem with GLA ARC-CE on the basis

of Oliver's comments (it was a publishing issue).

 

Oliver: still have the EMI3 migration ticket - the SE is now migrated,

the only thing left is the CREAM CE, which will simply be

decommissioned after the ARC CE is fully tested. (~weeks)

 

Gareth asked if Ewan talked to ATLAS about test jobs/queues on the ARC

CE (this is still pending).

AW: Upgrading to EMI3 ongoing. A little frustrating - the two services

pending (deployed a new CREAM CE, and were having pool account

mappings, resolved via NFS issues. Now ready to go, along with the

ARGUS server (resolved via help from DC and Iain Collier - the final

issue was that the ARGUS was talking to the CERN central banning, and

timing out, pointing it at the UK redirector was better). Also a new

BDII ready.

Put these all out and expected a sudden update and refresh but NAGIOS

didn't update. The issue seems to be that the *old* site BDII is being

looked at by (at least some) Top BDIIs (even though GOCDB has been

updated to reflect the new config).

 

There was some discussion over how this has broken  (the suggestion

was to ticket RAL or involve Stephen Burke).

 

Wahid has been working on bringing the new storage online (and is

planning to install directly to DPM 1.8.8 packages).

 

There was some discussion of how critical ARGUS Central Banning is to

the overall strategy.

DC: Tickets are as before - EMI3 (completed - APEL redeployment will

happen after this meeting).

Generally stable, other than ATLAS-job-brokering dearths.

 

Had comments back from Ewan re the website; now ready to pass the beta

site to DB, for comments. A note, the website is now updated from a

central (BitBucket hosted) repo.

 

People interested in monitoring may be interested in Monitorama, in

Portland, Oregon (currently ongoing).

 

GQ: The ARC CE currently passes UK Nagios tests. (The next step is to

deploy runtime env scripts on the WNs, as we don't have shared FS).

Next thing is to deploy a test Condor for investigation.

 

SS: Next storage plans (possibly HDFS/other block-distributed FS

backends). DPM Collaboration Meeting (they liked Wahid and I a lot).

monitorama looks good - I like the talk titles
